BURNER- FOR VAPOR-LAMPS.

Specification of Letters Patent No. 23,583, dated April 12, 1859.

To all whom it may concern:

Be it known that I, HENRY JoI-INsoN, of the city and county of Vashington, in the District of Columbia, have invented a new and Improved Domestic Self- Generating Fluid-Gas Apparatus; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure 1, is a side elevation. Fig. 2, is a front elevation. Fig. 3, is a section of generator and fluid pipe through a2.r Fig. 4:. Fig. 4c, is a section of generator through s-s of Fig. 1. Fig. 5, is a section of generator and gas pipe through 0 0 Fig. 4. Fig. 6, is a vertical section through burner. Fig. 7 is a vertical section through packing box,

key &c.

The nature of my invention consists in the improved construction and arrangement of the generator, burner, and packing box substantially as hereinafter set forth and described.

To enable others skilled in the art to make and use my invention I will describe its construction and operation.

In the several figures similar characters refer to like parts.

a is a key on which is a fine cut screw for regulating the flow of fluid to the generator, the end of this screw is turned off so as to form a conical valve fitting into a valve seat in pipe 0. Z), the packing box screwing on to pipe 0. b the cotton packing passing around key a, and held in place by screw box 6 pressing it up against pipe 0 and key a.

c is the fluid pipe and serves as case or nut to screw key (Z. d fluid pipe connecting with fluid reservoir. e, the shade holder. f, fluid pipe. 9, the burner. 71, the gas pipe leading from generator to burner. i the generator. 7', a plug in the opening a in generator. I cast the generator solid, and then drill cylinders or cavities 92, 0, Z. By thus constructing my generator I avoid the great difliculties arising from soldering &c., as in all other inventions for a similar purpose. After drilling cavity a plug 7' is permanently inserted by a screw or hole a may be placed in the rear of the generator m is a screw plug let in generator opposite cavity Z (see Figs. 8 and 4) for the insertion and removal of gauze wire plug, and also for convenience in cleanin 29, a screw pug let into generator opposite cavity 0 for convenience in cleaning it.

Q and are chambers in burner for the better heating and forcing out of the gas. 8 the flange of burner. t a screw plug so constructed as with the other portion of burner to form chambers g and g.

1, 1, are narrow slits or openings through that portion of screw plug t which separates chambers g and q:

In my invention it will be readily seen there is the utmost simplicity and ease of structure, no soldering or highly skilled workmanship. The generator as above described being cast and then drilled. That portion of pipes f and c and cl, shown in Fig. 7, is also cast solid and then drilled out as represented.

In operating my invention :The fluid is first placed in a suitable fountain and connected by pipes with pipe d, the torch used for lighting is then applied under the burner and generator, the key a is then slightly turned and the fluid by the weight of the head in fountain percolates up through gauze plugs and packing 70, into cavities Z and 'n the heat of these cavities by the action of the torch readily converts the fluid into gas; the gas then passes through cavity 0 into gaspipe h which it descends and passes into burner g,-as it enters the chamber 9 of burner it strikes against screw plug t which has also been highly heated by the torch, and thus keeps the gas at a suitable temperature;the gas then passes around plug 1, then up through openings 1, 1, by opposite currents into upper chamber g,where it is ignited at the lips of the burner and forms a beautiful light fully equal if not superior to coal gas. The effect of the gas entering upper chamber at opposite openings is to give the required pressure to the gas. The size of these openings regulates the flow of gas in such quantities as the burner demands. Thus it will be seen that these openings or orifices regulate the pressure and flow of the gas, and produces a regular, constant and brilliant light-which has not yet been accom plish ed by any invention for making gas from fluid. By this arrangement I am also enabled to use burners of any required size as used with coal or rosin gas lights. After lighting the gas the key a can be turned so as to admit a large or small flow of the fluid.

The advantages of my invention consist in the ease with which it can be made and put together, the readiness with which it can be taken apart for cleaning, the whole being put together by screws, the ability to change the burners when required, the simplicity and convenience of arrangement of shade holder, and the production of a steady light, an end never before accomplished.

I am aware that a fluid pipe for conveying the fluid to the generator is not new, nor is a tube for conveying the gas from the generator to the burner new; therefore I do not claim either of them as new or of themselves nor do I claim the thumb screw for regulating the flow of the liquid to the gen- 15 box I), constructed substantially as described, 20

in combination with gas pipe h, and fluid pipe f arranged and operating substantially as described and for the purposes herein set forth.
